10.4" Gemmy, Yellow Fluorite Crystals - Moscona Mine, Spain

Gemmy, Yellow Fluorite Crystals - Moscona Mine, Spain #188324

This is an large and alluring, 10.4" wide, lustrous yellow fluorite crystal cluster that formed in association with dolomite crystals, collected from the Moscona Mine in Asturias, Spain. The crystals are translucent, fluorescent and exhibit a beautiful yellow color. Under shortwave UV, these fluorite crystals fluoresce a faint white color. Some fluorite crystals from this locality will display gorgeous fluorescent phantoms within the cubic crystal, dependent on impurities present during formation.

This cabinet sized specimen is accompanied by a metal/acrylic (gibson) display stand.

About Fluorite

Fluorite is a halide mineral comprised of calcium and fluorine, CaF2. The word fluorite is from the Latin fluo-, which means "to flow". In 1852 fluorite gave its name to the phenomenon known as fluorescence, or the property of fluorite to glow a different color depending upon the bandwidth of the ultraviolet light it is exposed to. Fluorite occurs commonly in cubic, octahedral, and dodecahedral crystals in many different colors. These colors range from colorless and completely transparent to yellow, green, blue, purple, pink, or black. Purples and greens tend to be the most common colors seen, and colorless, pink, and black are the rarest.
